MacBook Pro 13" (2019) Battery Health at 83.9% despite Cycle Count at 164

First, the Battery Charge Cycle Count is utterly meaningless for battery health unless it is nearing 1,000 cycles. Why? If the person left the laptop connected to the power adapter most of the time, the cycle count would increase much slower.

That brings me to the next important item.....age of the battery is more important than the cycle count. Most Lithium Batteries tend to need replaced somewhere between 3 - 5 years on average.

Third, Coconut Battery is showing the actual battery health & what Apple would call "Maximum Capacity" is currently 83.6%. Either this is an older battery where it was left on the power adapter more than it was used on the battery, or if it is a new battery, then it is bad battery (likely a third party battery). Again, if you look closely at the information shown by Coconut Battery, you will see it clearly shows a manufacture date of "2019-11-11" which I'm assuming is the manufacture date of the battery due to where that information is located in the app.....and because there appears to be a laptop manufacture date of "2019-11-25" near the top of the app just under the Model Number.

Since that battery manufacture date is just before the laptop's manufacture date, it would appear you still have the original battery from the factory in this laptop....or a "new" battery that has been sitting around since 2019.

For the other contributors who I know doubt the information provided by some third party apps, I can say that Coconut Battery is providing accurate information. I have done a lot of digging into macOS to get battery health information so I can find better methods for testing the battery and can confirm the information shown in Coconut Battery is accurate from the data I pull from macOS itself using the command line (I cannot confirm the Manufacture Date since that is "coded" and I have not tried to check it myself, but I think it is likely to be accurate).

I have confirmed the information shown in Coconut Battery to be the same as shown using the "pmset -g rawbatt" command on the Intel Macs (the information from the "pmset" command for M-series Macs is broken for some values, but Coconut Battery manages to get the correct information from macOS through another command that is much harder to parse the output).

However, to my surprise, I notice through all known and trusted battery health softwares, ...

"Trusted"... by whom? Apple does not use such third party software.

There is only one authorized source for battery replacements, and that's Apple. If an aftermarket battery had been installed instead, it may not meet Apple's design capacity and it may also require frequent replacement. From what you describe that battery is not performing well, and is not likely to remain useful for very long.

I just want access Hardware diagnostics to check on, not only Battery Health, but also find out if there are any other problems with my hardware.

From what I see from Coconut Battery, the Apple Diagnostic would not report any battery issues.

The battery condition reported by macOS usually aligns with what the diagnostic will report so use that as a guide.

Unfortunately I have discovered that both macOS and the Apple Diagnostics have changed since the release of macOS 15.x Sequoia and it even affects the older versions of macOS (Sonoma & Ventura) that received the same updates patches & firmware as Sequoia whereby batteries are not showing as "Service Recommended" or failing the diagnostics even when the "Maximum Capacity" is less than 70% of the original Design Capacity, or when the Battery charge cycles is well over 1,000 cycles. Apple changed something in macOS/diagnostics and/or the system or battery firmware. It has been very frustrating since Apple won't allow a Battery Only repair price unless the battery shows as bad.

I've serviced enough of my organization's Macs to know them very well and to be able to notice this change.

So, my question... is my battery faulty? and how can I improve the actual hours of usage available on my battery (4 hours) and bring it closer towards the reported (3-9 hours)?

Yes, it dies sound like your battery is faulty.

And you do realize that the 4 hours you do get sits in the range 3-9 that you have targeted, yes?
